Grind the rivets off the old chain master link first instead of trying to force it out, as it'll be a PITA and you'll likely break the pin. The only other tip is to not be surprised how much force you'll have to use to actually spread the rivets on the new master link. I thought the thing was going to break when I did it, but it barely made a difference.
Ditto...use a dremmel and grind the the links flush (or slightly below) with the master link outter plate. Other than that, just pay attention when compressing the new links so as not to over compress causing the chain to bind.
